[Chronic central serous chorioretinopathy and photodynamic therapy: a case report]

Chronic central serous chorioretinopathy (CCSC) with recurrent and prolonged exudative retinal detachment may cause multiple degenerative manifestations with poor visual acuity. By acting on choroidal hyperpermeability, photodynamic therapy seems to be a useful treatment for symptomatic CCSC. We present the case of a 60-year-old patient presenting with symptomatic CCSC complicated with serous retinal detachment lasting more than 1 year. Visual acuity on the left eye was 1/20. Photodynamic therapy with indocyanine green angiography guidance was provided. Subretinal fluid was rapidly resolved and visual acuity improved to 7/10. Photodynamic therapy influences choroidal hyperpermeability and thus resolves serous retinal detachment in CCSC. Visual acuity improvement particularly depends on preexisting macular atrophy.
